HELP: After Z32 Caliper install

[mistaanime]

ok..i installed the z32 calipers on my 240sx..and then i bleed each caliper twice and still i have this problem..nothign happens until the petal is nearly almost to the ground..im using stock 5spd MC but should it have this big of a difference?

[sncs14]

nothing happens, or, "nealy nothing happens"?

If nothing happens and the pedal goes all the way to the floor you have the calipers on the wrong sides.

[mistaanime]

well..as im stepping the petal down..its not braking until the petal almost hits the ground..

[dct223]

did you bleed your ENTIRE brake system??? if you didnt then thats your problem

Rear right, rear left, front right, front left...

[mistaanime]

did the whole thing..i was thinking of juss re bleeding again but i dunno..

[sncs14]

Try adjusting the push rod that moves the BMC piston. It may not be contacting the BMC early enough. If the calipers are on the correct sides.

[aznpoopy]

bleed it again, and bleed the m/c too.

if they are junkyard calipers they could be fucked.
alternatively, your master cylinder could have gone to shit if its an old one. wouldn't be the first time.

[mistaanime]

calipers are on the right side..and i picked them up at NAPA..im thinkin its the master cylinder..but its juss that when i had the oem brakes on before..they they were breakin fine..bleeding the MC..haven't tryed that..tho that my be a problem because i've never and don't know how to bleed it....i juss know how to bleed the clutch...btw thanx for all these quick replies

[SimpleS14]

How did you bleed your brakes? Besides the order calipers your suppose to bleed in...did you build pressure on the pedal?

After I did mine, I stepped all the way on the pedal when bleeding the brakes...which was causing the brakes to work only when the pedal was almost to the ground. So second time around I stepped only half-way or where I would like the brakes to start grabbing and that solved my issue.

[DJPimpFlex]

^correct me if I'm wrong, but isnt the order, left rear, right rear, right front left front? I think thats how it is, and thats how I've awlays done it.

[mistaanime]

heh i did the proper order....but stepping it half way?..i could try to see if that works..juss thoguht some air mite stay in if i did it half way..

[dct223]

im not sure of the correct order.. but i always thought it was furthest away from the MC to the closest to the MC... thats what i did on my car and it worked...

Then that is what your missing...you have to do this to build resistance (or pressure) within the brake system. You won't get any air in your system given you keep your foot down half-way and whoever is underneath tightens the bleeder screw once all the air is out.


BTW....for a solo job I highly recommend speed bleeders. I have a set and I did the job faster than with two people.

your bleed valves are *up*, right?

that was my problem with my setup. I adjusted it and now it feels much better. BTW, I've got z32 30MM fronts and stock rears on an S14.

[nrg]

did you buy the right rotors for your calipers? it sounds like you have 30mm calipers with 26mm rotors.

This is what I say too.
Make sure that the bleed valves are not on the bottom side of caliper. If they are, you need to switch the sides the calipers are on.
I wouldn't be suprised if this was the problem.

If thats not it, try bench bleeding the MC and use teflon tape on all of the fittings between the hard lines and flex lines.

[infinitexsound]

im bettin that the bleeders arent up hence the issue... calipers are on the wrong side...

[mrmephistopheles]

btw, it's spelled 'PEDAL' with a big fat D

[mistaanime]

pedal..lol..ok thanx! anyways..yes its UP...heh the calipers are on the right sides..imma try the half step and then if that doesn't work then imma try adjusting the rod tomolo...thanx..and hopefully i'll get this fixed..
btw..mephisto...great sig..yours?

[mrmephistopheles]

my picture (i took it) but not my car.
It belongs to the boss of a friend of mine.
Keep an eye out for a big fat fucking pic thread coming soon.

[mistaanime]

i ended up buying a reverse pump with a container thing at a local kregan store..pumped out the air and got it done...i know there were the other ways..but..i had enough..and bothering some one to help me out was a pain..but with this...all it did was it sucked out the air outta the system pretty much a recycle device..anyways thanx for all your help!

[rossfashow]

did it help out can you brake fine now?

[theronin]

while u are still at the bleeding stage of ur brake job be sure to get some speed bleeders they save so much time...

[mistaanime]

hah bought some..and the retard sold me the wrong ones..he sold me the 10mm x 1.25 ones..i didn't know until i got home and looked it up on the internet..thats im suppose to be using 10mm x 1.5

[PITCH]

I dont have quite his problem but similar. Got the R33 GTS-T's fronts on only. (still waiting on parts for the rears) A little concerned. The pedal has some travel to it. Unforunately I had to make an emergency stop (figures, hrs after I did the install) And the pedal travel was hesitat and pretty soft. It did stop though. They stopped fine in normal crusing mode but that emergency stop took some time.

The only thing I didnt do was bleed the master cylinder should this be done? How do you do it?
Also I didnt blead the intire system. I just did the front calipers I swapped. Could this be the problem as well?

thanks..

[Tenchuu]

when i first bled my old Z32 calipers it was kinda soft and mushey, then i got super blue fluid, ends up it takes LONG AS HELL to do a complete flush of the system. and i found out that supposidily due to the way the lines are run the correct bleeding is cycle is lt rear, rt rear, rt front, lt front. it's all about getting massive amouts of air out of the system.

[sepulchral]

u monkeys you start at the wheel furthest from the MC and work your way towards it, damn

[NinjaGaiden]

for s13 nonABS, u want to bleed from the left rear first as tenchuu stated because it is the farthest line from the MC.

our hard lines come down the right frame rail and then split for the rear left and rear right calipers. The rear left is farthest away from the MC (not physically, but if you follow the hard lines, it is)
